NEEDLE-GUIDE FOR GLOVE-SEWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 630,474, dated August 8, 1899.

Application filed January 5, 1899- To all whom it may concern.-

Be it known that I, CHARLES OTTO WAG- NER, a subject of the Emperor of Germany, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Needle- Guides for Glove and Fur Sewing Machines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures.

Figure 1 of the drawings is a top plan view of the feed-disks of a fur and glove sewing machine, showing my improved needle-guide attached to one of the disk-supports. Fig. 2 is a view of the same parts, partly in side elevation and partly in central vertical section. Fig. 3 is an edge view of my improved needle-guide detached. 7

My improved needle-guide is adapted for use in glove and fur sewing machines such as shown in United States Patents Nos. 288,949 and 562,109.

The objects of my invention are to prevent injury by breakage or bending to theneedle and to provide a needle-adjusting guide.

The invention consists of a metallic bar adapted to be secured to a support and provided with a longitudinal guide-channel for the needle and an undercut bridge over the channel to guide and retain the needle in its channel and also to form a guide for properly adjusting the needle in its carrier.

It is well known to those acquainted with the art that the unequal resistances of different parts of the same piece of leather, either with or without the fur coating, tend to defleet a sewingqnachine needle and very frequently raise the needle from the channel of the needle-guide into the path of the transversely-moving looper, so that the looper engages and bonds or breaks the needle. I have ascertained that the breakage or bending of the needle can be wholly avoided by providing the guide with an undercut bridge over Serial No. 701,238. (No modeLl the needle-channel a short distance from its mouth, which prevents the needle from being deflected upward out of its channel and into the path of the looper.

Referring to the drawings, A and.A are the two disks which feed the fur or othermaterial to be sewed past the horizontally-reciprocatory needle A supported by the reciprocatory carrier A B is the needle-guide, which is secured by the screw B to the vertical spindle A, which supports the disk A, rotary thereon.

O is the looper, which is adapted to be reciprocated transversely of the guide and needle. 7 The operating parts are not shown, as these parts and their movements are well known and described in said Patents Nos. 288,949 and 562,109.

As heretofore constructed the needle-guide has been provided with a needle-channel like the needle-channel B open on its upper side throughout its entire length. My improved guide has a bridge-piece B which spans the needle-channel a short distance from its mouth B. The bridge is preferably undercut or beveled on its lower side to form the inclined surface B extending from its front to its rear' edge. Should the needle be deflected upward as it passes through the material, it Will strike the inclined surface and be forced down again into its channel out of the path of the looper before the looperpasses over the needle, wherein it is forcibly retained until the looper has passed over it. The rear edge B of the bridge serves also as a guide for properly adjusting the needle in its carrier, being so located that the eye of the needle will just come into View on the rear side of the bridge when properly adjusted and the needle-carrier is moved to the limit of its forward thrust.

It is obvious that the bridge may be made integral with the needle-guide bar, as shown, or it may be a separate piece secured to the bar in any known manner.

What I claim as new, and desire to secure the needle-channel is wholly vbridged rover,

substantially as described. a

a bar provided with a needle-channel and means for securing the bar to a support, of a guide-bridge crossing the channel ashort .distance from its mouth, and having its under surface inclined upwardly and toward the mouth of the channel, substantially as described.

8. Aneedle-guide for fur-sewing machines comprising a bar provided with aneedle-channel and means for securing the bar to a support, and having a bridge across the channel I with itsfront edge a short. distance from the mouth of the channel, and its rear edge at a 2. In a needle-guide, the combination with distance from the channel-mouth equal to the desired limit of inward thrust of the needleeye, whereby the rear edge of the bridgeserves as a guide for properlyadiusting a needle in its carrier, substantially as described.

In testimony whereof I have hereunto set any-hand this 3d day ofJanuary, 1899.

CHARLES OTTO. WAGNER.
